Abstract
BACKGROUND "Failure" is a term that is frequently used to describe an unfavorable outcome for patients who undergo surgical treatment for lateral ankle instability (LAI). A standard definition of failure for the surgical treatment of ankle instability has not been established by clinicians and researchers. PURPOSE To identify the definitions of ankle instability treatment failure that are currently in the literature and to work toward the standardization of the definition. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A systematic search of MEDLINE, SPORTDiscus, CINAHL, Embase, and Web of Science was conducted to identify clinical studies that included patients who underwent surgical treatment for LAI and included information about surgical failure. Studies with level of evidence 1 to 4 were included in this review. Animal studies, biomechanical studies, cadaveric studies, review articles, and expert opinions were excluded. The included studies were then reviewed for definitions of failure of any surgical procedure that was performed to correct LAI. RESULTS Of the 1200 studies found, 3.5% (42/1200) published between 1984 and 2021 met the inclusion criteria and were analyzed. After reviewing the data, we found numerous definitions were reported in the literature for LAI surgical failure. The most common was recurrent instability (40% [17/42]), followed by rerupture (19% [8/42]). For the original surgical procedure, the anatomic Broström-Gould technique was used most frequently (57% [24/42]). The failure rate of the Broström-Gould technique ranged from 1.1% to 45.2% depending on the definition of failure. CONCLUSION There were multiple definitions of failure for the surgical treatment of LAI, which is one of the reasons why the rate of failure can vary greatly. The literature would benefit greatly from the standardization of the definition of ankle instability treatment failure. This definition should include specific, objective physical examination findings that eliminate the ambiguity surrounding failure.

Abstract
BACKGROUND The utility of inferior extensor retinacular (IER) reinforcement for arthroscopic repair of a lateral ankle injury is debatable. We hypothesized that the outcomes would not differ significantly between arthroscopic all-inside anterior talofibular ligament (ATFL) repair with and without IER reinforcement. METHODS We prospectively randomized 73 patients who had arthroscopic all-inside ATFL repair into 2 groups: those who had IER reinforcement (37 patients) and those who had no IER reinforcement (36 patients). The primary outcome was the Karlsson Ankle Functional Score (KAFS). The secondary outcomes included the Foot and Ankle Outcome Score (FAOS), Tegner activity score (TAS), ankle range of motion, and radiographic parameters. The functional outcomes were evaluated preoperatively and at 6 and 12 months postoperatively. Stress radiographs were obtained preoperatively and at 12 months postoperatively. RESULTS The KAFS, all FAOS subscale scores, and TAS improved significantly at 1 year postoperatively in both groups, with no significant differences between the groups with respect to the preoperative and postoperative values. Significant differences were not observed between the ankle range of motion values recorded preoperatively and at 1 year postoperatively in both groups; the preoperative and postoperative range of motion values did not differ significantly between the groups. The mean talar tilt and talar anterior translation decreased significantly at 1 year postoperatively in both groups, with no significant differences between the groups preoperatively and postoperatively. One patient in each group had neuralgia of the superficial peroneal nerve; 2 patients in the IER reinforcement group had knot irritation causing mild discomfort. CONCLUSIONS Arthroscopic all-inside ATFL repair with and without IER reinforcement showed comparable functional and stress radiographic outcomes at 1 year. Performing IER reinforcement in addition to all-inside arthroscopic direct ATFL remnant repair is not necessary. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
Large osteochondral lesions (OCLs) of the shoulder of the talus cannot always be treated by traditional osteochondral autograft techniques because of their size, articular geometry and loss of an articular buttress. We hypothesised that they could be treated by transplantation of a vascularised corticoperiosteal graft from the ipsilateral medial femoral condyle. Between 2004 and 2011, we carried out a prospective study of a consecutive series of 14 patients (five women, nine men; mean age 34.8 years, 20 to 54) who were treated for an OCL with a vascularised bone graft. Clinical outcome was assessed using a visual analogue scale (VAS) for pain and the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. Radiological follow-up used plain radiographs and CT scans to assess graft incorporation and joint deterioration. At a mean follow-up of 4.1 years (2 to 7), the mean VAS for pain had decreased from 5.8 (5 to 8) to 1.8 (0 to 4) (p = 0.001) and the mean AOFAS hindfoot score had increased from 65 (41 to 70) to 81 (54 to 92) (p = 0.003). Radiologically, the talar contour had been successfully reconstructed with stable incorporation of the vascularised corticoperiosteal graft in all patients. Joint degeneration was only seen in one ankle. Treatment of a large OCL of the shoulder of the talus with a vascularised corticoperiosteal graft taken from the medial condyle of the femur was found to be a safe, reliable method of restoring the contour of the talus in the early to mid-term.

Abstract
Acute ankle injuries are among the most common injuries in emergency departments. However, there are still no standardized examination procedures or evidence-based treatment. Therefore, the aim of this study was to systematically search the current literature, classify the evidence, and develop an algorithm for the diagnosis and treatment of acute ankle injuries. We systematically searched PubMed and the Cochrane Database for randomized controlled trials, meta-analyses, systematic reviews or, if applicable, observational studies and classified them according to their level of evidence. According to the currently available literature, the following recommendations have been formulated: i) the Ottawa Ankle/Foot Rule should be applied in order to rule out fractures; ii) physical examination is sufficient for diagnosing injuries to the lateral ligament complex; iii) classification into stable and unstable injuries is applicable and of clinical importance; iv) the squeeze-, crossed leg- and external rotation test are indicative for injuries of the syndesmosis; v) magnetic resonance imaging is recommended to verify injuries of the syndesmosis; vi) stable ankle sprains have a good prognosis while for unstable ankle sprains, conservative treatment is at least as effective as operative treatment without the related possible complications; vii) early functional treatment leads to the fastest recovery and the least rate of reinjury; viii) supervised rehabilitation reduces residual symptoms and re-injuries. Taken these recommendations into account, we present an applicable and evidence-based, step by step, decision pathway for the diagnosis and treatment of acute ankle injuries, which can be implemented in any emergency department or doctor's practice. It provides quality assurance for the patient and promotes confidence in the attending physician.

Abstract
BACKGROUND We clinically and radiologically assessed mid- to long-term follow-up of a group of patients treated with a modified Watson-Jones technique for chronic ankle instability. METHODS Fourteen athletes were retrospectively evaluated with physical examination, and Tegner, Good and AOFAS scales; moreover, a 2-view stress, side-to-side X-ray, was performed. RESULTS All patients were followed-up at a mean of 10.8 years. No one reported further ankle sprains. Mean Good scale value decreased from 3.7 to 1.6, while the Tegner scale decreased from 6.8 to 5.1; the mean AOFAS score was 92.2. Mean sagittal-plane ROM was 62.3° (4.9° S/S difference), while mean coronal-plane ROM was 25.5° (3.8° S/S difference). Mean X-ray talar tilt angle was 4.5° (0.1° S/S difference), while mean anterior drawer test angle was 5.4 mm (0.5 mm S/S difference). CONCLUSIONS The modified Watson-Jones procedure seems to be a reliable technique in providing satisfactory mid- to long-term clinical and radiological results.

Abstract
This paper purpose is to suggest an in-depth approach to diagnose the causes and lesions associated with and consecutive to chronic ankle instability due to ankle collateral ligament laxity. The different therapeutic and medicosurgical options adapted to this diagnostic approach are identified. The diagnostic aim is to precisely locate the ligamentous injuries of the tibiofibular, subtalar, talar and calcanean system, to identify the predisposing factors such as the hindfoot morphology, and any lesions associated with chronicity: anterolateral impingement, fibular injury, osteochondral lesions of the talus dome and early osteoarthritis. Clinical tools are used in particular to identify areas of pain and for comparative analysis of mobility and laxity (ligament testing). There are also radiological tests, weight-bearing plain X-ray (stress X-ray), (alignment of the hind foot, with a Meary view [metal wire circling the heel], arthrosis), dynamic images to confirm and quantify laxity (manually, with a Telos device, with patient-controlled varus) and also more sophisticated techniques (ultrasound, CT arthrogramm, gadolinium enhanced MRI, MR arthrogramm) to identify ligament, tendon and cartilage damages. They are adapted to the lesions which have been identified in the diagnostic work-up: conservative first, to treat proprioceptive deficits (a new neuromuscular reprogramming technique which emphasizes muscle preactivation) and any static disorders (plantar orthotics); then surgical, to repair any collateral ligament (or sometimes subtalar) injury with three types of procedures: tightening the capsuloligamentous structures, ligament reconstruction with reinforcement (using the fibrous periosteum, the frondiform ligament (of Retzius) or tendinous reconstruction with the plantaris muscle, the peroneus tertius or even the calcanean tendon) and tendon tansfer procedures using all or part of the peroneus brevis (whole peroneus brevis and half peroneus brevis procedures). Any additional surgical procedures which may be indicated based on the results of the diagnostic work-up are performed at the same time as primary surgery when possible as needed (medial complex repair, calcaneal realignment osteotomies, talus osteochondral injuries debridment or fixation, anterior and posterior impingement suppression, tendon tears repair). The goal of this diagnostic and therapeutic approach is to stop the progression of laxity and to protect the ankle against degenerative arthritis, which is the main risk in these chronic conditions.

Abstract
BACKGROUND Chronic ankle instability (CAI) is a common orthopaedic entity in sport. Although other risk factors have been studied extensively, little is known about how it is influenced by the osseous joint configuration. AIM To study the effect of osseous ankle configuration on CAI. DESIGN Case-control study, level III. SETTING Radiological examination with measurement of lateral x rays by an independent radiologist using a digital DICOM/PACS system. PATIENTS A group of 52 patients who had had at least three recurrent sprains was compared with an age-matched and sex-matched control group of 52 healthy subjects. MAIN OUTCOME MEASURES The radius of the talar surface, the tibial coverage of the talus (tibiotalar sector) and the height of the talar body were measured. RESULTS The talar radius was found to be larger in patients with CAI (21.2 (2.4) mm) than in controls (17.7 (1.9) mm; p<0.001, power >95%). The tibiotalar sector, representing the tibial coverage of the talus, was smaller in patients with CAI (80 degrees (5.1 degrees )) than in controls (88.4 degrees (7.2 degrees ); p<0.001, power >95%). No significant difference was observed in the height of the talar body between patients with CAI (28.8 (2.6) mm) and controls (27.5 (4.0) mm; p = 0.055). CONCLUSION CAI is associated with an unstable osseous joint configuration characterised by a larger radius of the talus and a smaller tibiotalar sector. There is evidence that a higher talus might also play some part, particularly in women.

Abstract
This article describes the relevant surgical detail and MR imaging appearance of common operations performed in the foot and ankle. To evaluate postsurgical patients critically, it is important to understand the primary clinical diagnosis, surgical treatment undergone, the interval since surgery, and patients' current clinical symptoms. Radiography is the most common imaging modality for evaluation of the postoperative ankle and foot. MR imaging may be useful for evaluating the soft tissues and osseous structures in the postsurgical foot and ankle.

Abstract
BACKGROUND Symptomatic lateral ankle instability is a common source of disability in an active population. While most incidences are successfully treated by conservative measures, some individuals require lateral ankle reconstruction. A commonly performed procedure is the Gould modification of the Broström lateral ankle reconstruction. Despite its success, some individuals experience recurrent instability through reinjury. Revision surgery often involves nonanatomic reconstruction using tendon grafts that may restrict normal ankle and subtalar motion and can result in persistent postoperative pain and disability. The purpose of this study was to demonstrate an equivalent success rate using a more anatomic revision lateral ankle reconstruction based on the Gould modification of the Broström concept. METHODS We retrospectively reviewed 15 consecutive patients who had a revision lateral ankle reconstruction between 1992 and 2000. All procedures were done by a single surgeon (FGL). Patients who exhibited hindfoot varus and dynamic heel rollout had a valgus calcaneal osteotomy. Patients were asked to complete a 100-point questionnaire postoperatively. RESULTS All patients reported improvement in ankle function, decreased pain, and no episodes of instability compared to preoperative assessments. Excellent results were achieved in 12 of 15 patients which was consistent with published data from index Broström reconstructions. Four patients who had fixed hindfoot varus and dynamic ankle rollout had valgus calcaneal osteotomies. All patients returned to an active lifestyles including sports and military service. CONCLUSION Our findings suggest that a revision anatomic lateral ankle reconstruction is an effective option. A thorough clinical evaluation was mandatory to assess hindfoot valgus with dynamic ankle rollout for which a valgus calcaneal osteotomy was included in the procedure. We believe that tendon sacrificing procedures can be avoided in most patients, but soft-tissue structures must be assessed intraoperatively and the surgical approach planned to allow for conversion if necessary.

Abstract
Six patients were retrospectively identified as having undergone lateral ligament reconstruction surgery. The surgical procedures were categorized into four groups: direct lateral ligament repair, peroneus brevis tendon rerouting, peroneus brevis tendon loop, and peroneus brevis tendon split and rerouting. At radiography and magnetic resonance (MR) imaging, the presence of one or more suture anchors in the region of the anterior talofibular ligament indicates direct ligament repair, whereas a fibular tunnel indicates peroneus brevis tendon rerouting or loop. Both ultrasonography (US) and MR imaging demonstrate rerouted tendons as part of lateral ankle reconstruction; however, MR imaging can also depict the rerouted tendon within an osseous tunnel if present, especially if T1-weighted sequences are used. Artifact from suture material may obscure the tendon at MR imaging but not at US. With both modalities, the integrity of the rerouted peroneus brevis tendon is best evaluated by following the tendon proximally from its distal attachment site, which typically remains unchanged. The rerouted tendon or portion of the tendon can then be traced proximally to its reattachment site. Familiarity with the surgical procedures most commonly used for lateral ankle ligament reconstruction, and with the imaging features of these procedures, is essential for avoiding diagnostic pitfalls and ensuring accurate assessment of the ligament reconstruction.

Abstract
Twenty-eight ankles in 27 patients with chronic instability were treated with a modification of the Evans procedure during a 10-year period. The diagnosis was assessed by clinical evaluation and radiographic stress tests. The reconstruction procedure consists of using the peroneal brevis tendon to repair ankle instability and restore the loss of anatomic integrity of the injured structures. Twenty-five patients (26 ankles) were available at a mean followup of 99.6 months or 8.3 years (range, 28-117 months). Midterm results were evaluated using the ankle-hindfoot score of the American Orthopaedic Foot and Ankle Society, and postoperative radiographic stress tests. According to this scoring system, the current reconstruction procedure resulted in 92.64 points (range, 63-100 points). However, moderate restriction in hindfoot inversion was seen in nine patients (34.61%). Three ankles (11.5%) had a positive anterior drawer sign (> 8 mm). In five ankles (19.2%), there were mild degenerative joint changes. Therefore, the current reconstruction method led to a satisfactory clinical and functional midterm outcome shown by a numeric scale.

Abstract
BACKGROUND Very little objective data are available regarding medial ankle instability. HYPOTHESIS Several structures contribute to the stabilization of the medial ankle, and, in the case of injury, they are not involved in a uniform way. STUDY DESIGN Explorative, prospective case series. METHODS Fifty-one patients (52 ankles; males 27, females 25; age 36.4 [16 to 60] years) were surgically treated because of medial ankle instability. All clinical findings and structural changes, as found by arthroscopy and surgical exploration, were compared with the clinical diagnosis and then addressed for surgical reconstruction. RESULTS Pain in the medial gutter was noted in all ankles (100%). Arthroscopy verified a clinically expected additional lateral instability in 40 ankles (77%). At 4.43 years (2 to 6.5 years) after surgical reconstruction, the clinical result was considered to be good/excellent in 46 cases (90%), fair in 4 cases (8%), and poor in 1 case (2%). CONCLUSION The clinical characteristics of medial ankle instability are a feeling of giving way, pain on the medial gutter of the ankle, and a valgus and pronation deformity of the foot that can typically be actively corrected by the posterior tibial muscle. Arthroscopy was shown to be a very helpful diagnostic tool in verifying medial instability.

Abstract
BACKGROUND There are little objective data on structural changes of the chronically unstable ankle. Such knowledge could help with preoperative planning. HYPOTHESIS Preoperative ankle arthroscopy provides important insights into the causes and mechanisms of ankle instability and the resulting disability. STUDY DESIGN Case series. METHODS From 1993 to 1999, arthroscopic examination was performed in the ankles of 148 patients with symptomatic chronic ankle instability that had lasted 6 months or more. All structural changes were recorded and compared with the clinical diagnosis. RESULTS A rupture or elongation of the anterior talofibular ligament was noted in 86% of ankles, of the calcaneofibular ligament in 64%, and of the deltoid ligament in 40%. Cartilage damage was noted in 66% of ankles with lateral ligament injuries, whereas 98% of the ankles with deltoid ligament injuries had cartilage damage. Although lateral instability could be verified arthroscopically in 127 patients, medial instability was presumed clinically in 38 patients but was actually detected in 54 patients arthroscopically. CONCLUSION Preoperative ankle arthroscopy revealed an essential amount of information that would otherwise have been undetected. For instance, the ligaments showed typical abnormalities corresponding to different entities of ankle instability and different intraarticular pathologic conditions.

Abstract
Lateral ankle sprains are among the most common sports injuries. Although ankle sprains are treated conservatively at the present time, for years the treatment was based on acute repair of the ruptured ligaments. Several differing opinions currently exist as to the treatment of lateral ankle sprains. A review of the literature and explanation of the benefits and risks of each treatment protocol is undertaken.

Abstract
OBJECTIVE The purpose of this study was to quantitatively examine the flexibility of sprained ankles using an arthrometer device and compare the differences in flexibility between ankles following the first sprains and ankles with repeated severe sprains and chronic symptoms. DESIGN A retrospective in vivo study was used. BACKGROUND Many in vitro studies have demonstrated a significant role of joint flexibility in determining mechanical laxity of human cadaveric ankles after sectioning of the lateral ligaments, but few in vivo studies have used the technique to provide objective measurement on the sprained ankles. Furthermore, there is a lack of extensive studies that compared the difference in the ankle flexibility between ankles following the first sprain and ankles with multiple repeated severe sprains and chronic symptoms. METHODS A total of 27 subjects with unilateral ankle sprains participated in this study. The subjects were divided into a first injury group (group A, n=12) and a chronic symptom group (group B, n=15) based on the history of their ankle injuries. The ankle flexibility in anterior drawer and inversion/eversion tests was measured in both ankles of the subjects using an arthrometer device, the ankle flexibility tester -- a six-degree-of-freedom instrumented linkage used for measurements of applied forces/moments and resultant rotations and/or translations of the ankle joint complex. The difference in ankle flexibility between the injured ankle and the contralateral intact side was analyzed. RESULTS The flexibility in anterior drawer test of the injured ankles significantly increased compared to the intact ankles of the same individual in group B, but the same difference was not significant in group A. There were more subjects in group B (46.6%) than in group A (33.3%) who showed a sign of mechanical laxity in their injured ankles. CONCLUSIONS The results indicated that the approach with measurement of ankle flexibility may be a potential tool used to detect the mechanical laxity in the sprained ankles. A tendency was found that patients with multiple ankle sprains and chronic symptoms had a higher occurrence rate of mechanical laxity. The result of the present study may also be interpreted that the ankles with mechanical laxity had higher risk of re-injury and leading to chronic symptoms.

Abstract
BACKGROUND Ruptures of the lateral ankle ligaments are very common; however, treatment remains controversial. The aim of the current study was to perform a meta-analysis of randomized, controlled clinical trials of existing treatment strategies for acute ruptures of the lateral ankle ligaments. METHODS Randomized, controlled trials reported between 1966 and 1998 were included if they involved acute ruptures of the lateral ankle ligaments. Randomized, controlled trials are defined as comparative studies with an intervention group and a control group in which the assignment of participants to a group is determined by the formal procedure of randomization. Summary measures of effectiveness were expressed as relative risks with use of random effects modeling. RESULTS When analyzing the trials, we searched for comparable outcome measures in both short and long-term follow-up studies (studies with six months to 3.8 years of follow-up). This resulted in the analyses of three outcome measures: time lost from work, residual pain, and giving-way. This report summarizes the results of twenty-seven trials. With respect to giving-way, a significant difference was noted between operative treatment and functional treatment (relative risk, 0.23; 95 percent confidence interval, 0.17 to 0.31) in favor of operative treatment and a significant difference was also noted between functional treatment and treatment with a cast for six weeks (relative risk, 0.69; 95 percent confidence interval, 0.50 to 0.94) in favor of functional treatment. With respect to residual pain, no significant difference was found between operative and functional treatment and a significant difference was found between functional treatment and treatment with a cast for six weeks (relative risk, 0.67; 95 percent confidence interval, 0.50 to 0.90). We found minimal or no treatment to result in more residual pain (relative risk, 0.53; 95 percent confidence interval, 0.27 to 1.02) and giving-way (relative risk, 0.34; 95 percent confidence interval, 0.17 to 0.71) than did functional treatment. CONCLUSIONS We concluded that a no-treatment strategy for ruptures of the lateral ankle ligaments leads to more residual symptoms. Operative treatment leads to better results than functional treatment, and functional treatment leads to better results than cast immobilization for six weeks.

Abstract
Injury to the lateral ligaments of the ankle is one of the most common sports-related injuries. Although these injures generally resolve with non-operative treatment reconstruction of the lateral ligaments of the ankle is occasionally necessary. We report the surgical technique and result of reconstruction of the anterior talo-fibular ligament using a semi-tendinosis free graft in 26 patients with an average follow-up of 24 months. 81% of patients reported complete resolution or substantial improvement in instability, swelling and sharp pain. Episodes of functional instability persisted in five patients post operatively. No significant differences were noted between the operated and contra-lateral non-operated ankle in range of motion or uniaxial balance assessment. Kin-Com testing of hamstring strength showed no differences between sides. Short term results suggest that this ligament reconstruction provides good results without sacrifice of peroneal function and has minimal donor site morbidity.

Abstract
This study represents a preliminary review of 10 patients having undergone arthroscopic monopolar thermal stabilization for ankle instability from October 1996 to June 1998. All patients in this study expressed mild to moderate chronic ankle instability complaints and were dissatisfied with their attempts at conservative care. Subjective clinical results were evaluated in all patients having undergone this procedure utilizing a modified version of the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale. In addition, eight of these patients underwent pre- and postoperative stress radiographs. The average age of the patient population in this study was 34.5 +/- 9.26 years. The preoperative AOFAS scores averaged 58.3 +/- 8.96 and the postoperative were 88.1 +/- 11.09 points. Patients returned to full activities on the average of 3 months. Postoperative ankle varus stress test reduced on the average of 2.8 degrees +/- 2.77 degrees, while the anterior drawer measurements reduced 4.8 +/- 1.83 mm. The reduction in anterior drawer test amounted to an approximate 60% decrease in talar excursion postoperatively. All patients who underwent this procedure achieved ankle stability and commented that they would undergo the procedure again.

Abstract
The palmaris longus tendon was used to reconstruct the anterior talofibular ligament (ATFL) in 27 ankles with chronic lateral instability. The mean age of the patients at surgery was 23 years, and the follow-up was more than 2 years. The functional evaluation showed excellent or good results in all ankles. Twenty-seven ankles were divided into two groups according to operative findings: group A consisted of 11 ankles with old isolated injury of the ATFL, and group B consisted of 16 ankles with old combined injuries of the ATFL and the calcaneofibular ligament. There were no significant differences in clinical results between group A and group B. The preoperative mean talar tilt angles on stress radiograph in group B were significantly larger than those in group A. At follow-up, there were no significant differences in the mean talar tilt angles between group A and group B. We demonstrate that reconstruction of the calcaneofibular ligament along with the ATFL is not necessary for patients with chronic combined lateral ligament instability.

Abstract
The present study investigated the effects of two different surgical procedures for the treatment of chronic ankle instability. Ten patients treated with an anatomic reconstruction using a periosteal flap were compared with a second group that received an Evans tenodesis. All patients were evaluated before and after surgery with clinical and radiographic examinations as well as dynamic pedobarography. Patient satisfaction and radiographic and functional results were comparable in both groups and revealed a good restoration of joint stability and gait symmetry. Our results indicate that both methods of ankle ligament reconstruction achieve a comparable clinical and functional outcome within 1 year after surgery.

Abstract
PURPOSE The aim of this paper is to provide fundamental information about the biomechanics of the unstable ankle joint and to establish a rational for the daily clinic when dealing with patients in both, the acute and chronic unstable condition of the ankle joint complex. METHODS The problem of the unstable ankle joint is worked up by analyses of the basic anatomy and biomechanics followed by an overview of its clinical manifestation including a differential diagnosis. RESULTS The ankle joint and its surrounding ligaments represent a complex mechanical structure whose mechanical properties highly depend on ligament integrity. Recent in vitro studies have supported the hypothesis that, besides maintaining lateral ankle stability, the lateral ankle ligaments play a significant role in maintaining rotational ankle stability and in transferring movement between leg and foot. Instability of the ankle results from acute ligament injuries and may become chronic when complete ligament healing does not occur. Chronic instability syndrome may manifest with recurrent injuries with chronic lateral pain, tenderness, swelling, or induration with great difficulties in sports and daily activities. Symptomatic instability can be caused by mechanical instability with demonstrable instability, but it can be also present with no demonstrable instability. Impairment of ankle proprioception has been shown to be a major cause of symptomatic ankle instability. Other conditions may mimic ankle instability. CONCLUSIONS The cause of chronic functional instability is often not mechanical instability but impairment of ankle proprioception. A history of insecurity, instability, and giving way is far more important in diagnosis than the physical and radiographic examination. If surgical treatment is advised, anatomical reconstruction of the ankle ligaments is mandatory for fear of altering the biomechanics.

Abstract
OBJECTIVES To determine long-term results of patients who underwent primary ligament repair and delayed reconstruction for lateral ligament instability. DESIGN Retrospective. SETTING Outpatient clinic. PATIENTS/PARTICIPANTS Patients who had undergone acute repair or delayed reconstruction at this institution between 1958 and 1977, excluding patients who were deceased or who could not be located. INTERVENTION Forty-eight patients (fifty-three ankles) underwent twenty-two primary ligament repairs and thirty-one delayed reconstruction operations. MAIN OUTCOME MEASUREMENTS Clinical results graded with clinical scale and radiologic results based on stress radiographs and plain film radiographs. RESULTS At an average of twenty years after operation (range 12 to 33 years), patients were satisfied with forty-nine ankles, satisfied with reservations with two ankles, and dissatisfied with two ankles. Clinical results after repair were excellent in twenty ankles, good in one, fair in none, and poor in one. After reconstruction, the results were excellent in twenty-one ankles, good in six, fair in one, and poor in three. In the primary repair group, the mean talar tilt with stress testing improved from 20.7 +/- 10.7 degrees before operation to 2.8 +/- 3.0 degrees after operation. In the reconstruction group, the mean talar tilt improved from 20.7 +/- 8.4 degrees before operation to 2.8 +/- 3.5 degrees after operation. CONCLUSIONS Clinical and radiologic results were similar in the repair and reconstruction groups. The majority of severe (Grade III) ankle sprains may be treated nonoperatively, but if residual instability occurs, late reconstruction should achieve satisfactory results.

Abstract
Between 1979 and 1994, 75 patients underwent primary repair of a Grade III rupture of the lateral ligament of the ankle. The operation was indicated after the demonstration of ankle instability on stress X-rays by anterior displacement of the talus by more than 8 mm or/and a talar tilt of more than 10 degrees. The patients were either young or engaged in sports activities or physically demanding jobs. An end-to-end suture of the torn ligament was undertaken under general anaesthesia. A non-weight-bearing cast was used for the first 2 weeks, followed by a walking cast until 6 weeks postoperatively. Sixty-one patients were followed up for 1-15 years (mean 10.3 years). At follow-up all but one patient had returned to their pre-injury level of activity without complaint or restriction.

Abstract
The effect of reconstruction of the anterior talofibular ligament with the Chrisman-Snook procedure on neutral zone laxity (anterior-posterior displacement at low loads) and flexibility (a measure of the nonlinear load-displacement response) of the ankle was investigated in vitro during the anterior drawer test. Neutral zone laxity was defined as the magnitude of anterior-posterior displacement of the ankle joint at +/- 2.5 N of applied load. The flexibility parameter was defined as the slope of a line between the natural logarithm of the anterior load applied to the ankle and the resulting displacement. After reconstruction with the Chrisman-Snook procedure, the values for neutral zone laxity of the ankle were significantly less than normal at 0 degree of plantar flexion, whereas the flexibility values were significantly greater than normal. This study revealed that, after the Chrisman-Snook procedure, values for ankle flexibility are not restored to normal even if those for neutral zone laxity are reduced to less than normal. The findings suggest that this nonanatomical reconstruction procedure does not reproduce normal kinematics of the ankle joint. This may help explain some of the adverse clinical reports associated with the Chrisman-Snook reconstruction procedure.

Abstract
To evaluate grading methods used to report clinical results, we reviewed 1,607 articles related to the foot and ankle published in six orthopaedic journals from 1980 through July 1993. Many clinical studies use criteria such as patient satisfaction to grade results. A numeric score or grade was used in 346 articles: 238 used a grade only, 90 used a numeric score and grade, and 18 used a numeric score only. The numeric score or grade was usually, but not always, reported with details of the individual clinical factors that composed the score or grade. Twenty-three articles used a score before and after treatment. Statistics were used in 62 articles, and in 6 of those the statistics were used to compare clinical condition before and after treatment. This study demonstrated the array of grading methods used in selected orthopaedic journals and indicated the need for standardized grading techniques to allow for more meaningful interpretation of the orthopaedic literature.

Abstract
Lateral ankle instability can present as either acute or chronic. Proper identification of the etiology is necessary to determine the proper treatment plan. The Brostrom-Gould procedure, when properly used, can provide adequate correction of the unstable ankle. A review of the procedure, its indications, and the results of 44 patients who underwent the procedure will be discussed.

Abstract
A new procedure is described that uses a split peroneus longus tendon to reconstruct the anterior talofibular and calcaneofibular ligaments for chronic post-traumatic lateral ligamentous instability of the ankle for patients who wish to return to sporting activities. Subtalar inversion, which is essential for many sporting activities, is not affected. It is not a difficult procedure. In this small series of four patients followed out of six, over a period of 6 years with an average follow-up of 31.7 months, it has given good results, both subjectively and objectively, enabling them to return to active sports.

Abstract
We treated 19 patients for chronic ankle instability with a modified Evans procedure. All patients were evaluated after an average follow up of 128 months with detailed questionnaire, clinical examination, and stress radiographs. Although the subjective results were reported as 8 excellent, 7 good, and 4 fair, residual pain was reported by 11 patients. There was a significantly increased number of osteophytes in the treated ankle joint. Stress radiographs demonstrated significantly improved stability in the operated ankle joint. Range of motion was significantly reduced in hindfoot inversion. The results showed that the modified Evans procedure achieved sufficient joint stability at the expense of inversion range of motion. This reconstruction method apparently did not prevent the development of arthrosis.

Abstract
Eighteen intact ankles were loaded with inversion-eversion and anterior-posterior forces, and motions of the talus and calcaneus were measured. Ankles were tested in neutral, 15 degrees of dorsiflexion, and 15 degrees of plantar flexion. The anterior talofibular ligament was then sectioned and testing was repeated. In half the specimens the calcaneofibular ligament was also sectioned followed by repeat testing. The Evans, Watson-Jones, and Chrisman-Snook procedures were performed on each ankle and testing was repeated. With inversion-eversion loading, only the Chrisman-Snook reconstruction resulted in a significantly more stable ankle joint complex than in the anterior talofibular ligament cut ankles. All three reconstructions increased ankle stability over the anterior talofibular and calcaneofibular ligament cut state. With anterior-posterior loading, all reconstructions resulted in a significantly more stable ankle joint complex than the anterior talofibular ligament cut ankles. The Evans and Chrisman-Snook procedures resulted in more stability than the anterior talofibular and calcaneofibular ligament cut ankles. There was no difference in subtalar joint motion with inversion-eversion loading among ankles with the anterior talofibular ligament cut and those with any of the reconstructions. For the anterior talofibular and calcaneofibular ligament cut ankles, subtalar joint motion was similar to that in intact ankles after each reconstruction. All three reconstructions resulted in ankles with significantly less subtalar joint motion with anterior-posterior loading than ankles with the anterior talofibular ligament cut or with the anterior talofibular and calcaneofibular ligaments cut. The Chrisman-Snook procedure resulted in ankles with significantly less motion than intact ankles.

Abstract
We followed 38 patients with chronic ankle instability treated by a modified Evans procedure. Evaluation at an average of 68 months follow-up included a standard clinical questionnaire and examination, radiological procedures, and gait analysis. Plantar pressure distribution measurements were recorded during walking and were compared with data from a group of normal subjects (N = 100). The subjective patient questionnaire revealed 87% good or excellent results, but residual pain was reported by 40% of the patients. The gait analysis indicated a significant increase in midfoot loading (22%) consistent with an observed restriction of inversion after surgery. However, the plantar pressure changes were not associated with poor clinical outcome. We cannot say whether these increased pressures will be associated with long-term outcome.

Abstract
The static restraints of various surgical procedures for chronic lateral ankle instability were compared. Forty cadaveric ankles were divided equally into the following five groups: 1) ankles with intact anterior talofibular and calcaneofibular ligaments, 2) ankles with incised anterior talofibular and calcaneofibular ligaments, 3) ankles with Chrisman-Snook procedure, 4) ankles with Watson-Jones procedure, or 5) ankles with modified Broström procedure. All ankles were placed in a mechanical apparatus for anterior drawer stress and inversion stress tests. After each application of force, a radiograph of the ankle joint was taken, and the anterior talar displacement and the talar tilt angle were measured. All procedures reduced anterior drawer and talar tilt when compared with the ankles with incised anterior talofibular and calcaneofibular ligaments. Significant differences were found among the groups for both inversion and anterior drawer stress at all forces, except for the third and fourth groups. The modified Broström group had the least amount of anterior talar displacement and talar tilt angle at all forces. There were no significant differences between the Watson-Jones and the Chrisman-Snook procedures in anterior talar displacement and talar tilt. The modified Broström procedure produced a greater mechanical restraint than either of the other procedures.

Abstract
The anatomy of the lateral ankle ligaments that is frequently described in articles and book chapters often lacks the precision of orientation and attachment points. We believe a knowledge of this precise anatomy is important to better reconstruct or repair lateral ligaments. We dissected cadaveric ankles free of skin and soft tissue and made the following measurements: areas of attachments of the anterior talofibular ligament, length and width of the anterior talofibular ligament, and locations of the attachments on the fibula and talus. The same measurements were made of the calcaneofibular and posterior talofibular ligaments. The distance of the calcaneofibular calcaneal attachments from the subtalar joint as well as the angle in the sagittal plane with the fibula was determined. We then used these anatomic attachments of the ligaments to make comparisons with the Watson-Jones and modified Elmslie reconstructions. Our results enable us to suggest a more anatomic placement for ligaments in a reconstruction.

Abstract
Chronic lateral ankle instability may be present in as many as 10% to 30% of people suffering from acute lateral ankle ligament injuries. Ankle instability has been referred to as either functional instability or mechanical instability. Management options consist of either nonoperative or operative treatment, with the majority of the literature emphasizing operative management for chronic instability. Long-term studies assessing the different types of available operative repairs have now been published. This review article discusses chronic lateral ankle ligament instability from a functional, anatomical point of view. The indications for treatment, nonoperative and operative treatment, as well as the biomechanical information available regarding these methods of treatment are considered. The major emphasis of this review is discussion and analysis of the many different surgical treatment options. Following this review, we presently recommend anatomical repair to the bone of both the anterior talofibular ligament and the calcaneofibular ligament, together with imbrication of the ligaments. In patients with hypermobility, long-standing instability, or arthritis, reconstruction using the Chrisman-Snook technique is recommended.

Abstract
The results of treatment of chronic ligamentous insufficiency of the lateral hindfoot using plantaris tendon grafting (52 ankles) or peroneal tenodesis (128 ankles) were compared with an average followup of 66 months. In two-thirds of all cases an instability of the subtalar joint was present, isolated or combined with an instability of the talocrural joint. The overall outcome with both methods was good, but the results after plantaris repair were slightly more favorable. This fact is underlined by the frequency of reoperations: 1.9% after plantaris repair compared with 9.4% after peroneal tenodesis. We conclude that plantaris repair is the method of choice.

Abstract
The average general orthopaedic surgeon examines and treats a considerable number of acute lateral ankle ligament sprains in a busy office practice. A cursory review of recent articles published on this subject will present a confusing picture regarding diagnosis and treatment of Grade III injuries. An air of controversy surrounds the interpretation of diagnostic x-rays, and the management of these common ankle problems. This review article is presented to summarize current thoughts on the anatomy, biomechanics, diagnosis, and treatment of acute lateral ankle ligament sprains.

Abstract
The ankle and subtalar joints form a coupling which acts like a universal joint. When the anterior talofibular ligament is disrupted, rotation of the talus about the long axis of the leg is permitted. This abnormal rotation in the transverse plane is the distinguishing feature of rotary ankle instability. The pathomechanics of rotary ankle instability are described. A simple and direct approach to repairing and reinforcing the anterior talofibular ligament and the results of 37 consecutive delayed reconstructions by this method are reported. Advantages of this procedure are felt to be a restoration of the original anatomy, preservation of the peroneal tendons, maintenance of the integrity of the subtalar joint and excellent postoperative results. Disadvantages include a lack of objective diagnostic criteria.

Abstract
Sixty patients with chronic lateral functional and mechanical instability of the ankle joint were treated with shortening and reinsertion of the lateral ankle ligaments. All patients were followed prospectively for 2 to 5 years (mean, 3 years 6 months). We found the functional results to be excellent or good in 53 patients (88%). Patients with unsatisfactory results had either generalized joint hypermobility or long-standing ligament insufficiency. Anterior talar translation (ATT) and talar tilt (TT) were measured radiologically on standardized radiographs. Patients with excellent and good functional results had better mechanical stability, both ATT and TT, than those with fair and poor functional results. A good correlation was found between clinical, functional, and radiological results. In conclusion we found that reconstruction of the ankle stability by shortening and reinsertion of the lateral ankle ligaments is a safe and simple method and is a good alternative to other more complex methods of ligament reconstruction. The method should, however, be used with great care in patients with generalized joint hypermobility or in patients with long-standing ligament insufficiency.

Abstract
Lateral ankle instability syndrome is defined by pain and instability caused by ligament laxity. Anterior talofibular ligament laxity, with or without calcaneofibular laxity and other abnormalities, is often present in conjunction with peroneus brevis tendon tears, abnormal ligament placement, tibialis posterior tendon tears, osteochondritis dissecans, arthritis, synovitis, loose bodies, and tarsal coalition. Surgical reconstructions were performed on 43 ankles using a split peroneus brevis tendon graft routed through osseous tunnels in the talus, fibula, and calcaneus and resutured to the reconstructed anterior talofibular and calcaneofibular ligaments. The tunnel locations, transfer routes, and tendon reinforcement were modifications based on the Elmslie procedure. Good and excellent results were achieved in 91% of the patients. Ninety-eight percent of the patients achieved stability. Followup was from 9 months to 11 years. Twenty-one patients had preoperative and intraoperative findings that required additional procedures. Thorough evaluation of patients with lateral ankle instability syndrome increases the frequency of finding associated abnormalities, which if left uncorrected, may adversely affect the outcome of surgery.

Abstract
A modified Watson-Jones tenodesis using a split of the peroneus longus for correction of chronic lateral ankle instability has been used in a series of 43 ankles. The range of follow-up varied between 2 and 10 years (median 56 months). Functional stability was achieved in most cases. One of the major aims of this study was to analyze the different aspects related to persisting symptoms. The need of a standardized rating system for comparison of the results of the various types of reconstruction procedures is emphasized.

Abstract
To study the incidence of fibulocollateral ligament ankle sprains in the young male athlete, a survey of 84 varsity basketball players was done. Seventy percent of the players had a history of an ankle sprain. Eighty percent of those with a positive history had multiple sprains. Most of the injuries were mild, but in 32% of the injuries, the athlete missed more than 2 weeks of play. No medical attention was sought in 55% of the cases. About 50% of the athletes with a sprain had residual symptoms from their injuries; 15% of the injured athletes felt that their residual symptoms compromised their playing performance. This article emphasizes the potential seriousness of the ankle sprain in the young athlete and presents a recommended method of management, including assessment of severity, treatment, and rehabilitation.

Abstract
The purpose of this study was to investigate the biomechanical behavior of human anterior talofibular and calcaneofibular ligaments, as well as peroneus brevis, split peroneus brevis, and toe extensor tendon grafts. This article represents the first published data comparing the most frequently injured ankle ligaments to the most commonly used autogenous reconstructive grafts. Twenty fresh human ankles provided the bone-ligament-bone and tendon graft specimens for biomechanical testing on a Minneapolis Testing System. Protocol consisted of cyclic loading at physiologic deflections, followed by several load-deflection tests at varying velocities, followed by a final extremely rapid load to failure test. The load-deflection data for all ligaments and tendons demonstrated nonlinearity and strain rate dependence. The maximum load to failure for the anterior talofibular ligament was the lowest of all specimens tested, while its strain to failure was the highest. The loads to failure of the peroneus brevis and split peroneus tendons were significantly greater than the anterior talofibular ligament and approximately equal to the calcaneofibular ligament. Strains to failure for all tendons were significantly less than ligament strains. The high strain to failure of the anterior talofibular ligament demonstrates its physiologic function of allowing increased ankle plantar flexion-internal rotation, while its low load to failure shows its propensity for injury. The greater strength of the tendon grafts explains the success of most reconstructive procedures in reestablishing stability in chronic ankle sprains; at the same time, the data presented suggest that those surgical procedures sacrificing the entire peroneus brevis tendon are unnecessary.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The sprained ankle is one of the most common musculoskeletal injuries. Three treatments for severe acute sprain are advocated: immobilization, protected mobilization, and primary surgical repair. These injuries are cared for by different medical and paramedical specialties, each with varying skills and interests. In order to define the current preferred treatment, a survey was randomly distributed to 500 physicians. These data indicate that the treatment is generally conservative: cast immobilization was the preferred treatment for the moderate and severe sprain. These data also demonstrated that basic care (e.g., ice and elevation) and rehabilitation were often neglected. Significant differences were noted between the specialties of orthopaedic surgery, family practice, and emergency medicine.

Abstract
Chronic lateral ankle instability is a costly disability to the athlete. The Chrisman-Snook and Evans lateral ligamentous reconstructions are two procedures frequently performed to correct ligamentous instability. The entire peroneus brevis tendon is transected in the Evans procedure, thus sacrificing its eversion strength and power. The importance of preserving the eversion function of the peroneus brevis muscle is speculative, but may be of significance for good long-term results. The ankle eversion strength and power of 10 patients with Chrisman-Snook and 10 patients with Evans lateral ligamentous reconstructions were objectively evaluated with the Cybex II Isokinetic Dynamometer. The mean postoperative time to testing was 4.2 years. The uninvolved ankle was also tested and used as the normal strength of the patient. Twenty normal controls matched for age, sex, and physical activity were tested to assure maximum test reproducibility. The eversion strength was tested at several speeds, but torque values at speeds of 30 and 120 deg/sec were selected for analysis. At slow speeds, 30 deg/sec, and ankles that had Evans and Chrisman-Snook reconstruction were 4% and 7% weaker, respectively, than the contralateral normal ankles. At 120 deg/second the ankles were 8% and 9% weaker with the Evans and Chrisman-Snook reconstructions, respectively. A three factor analysis of variance with repeated measures on two of the factors was used to analyze the data.(ABSTRACT TRUNCATED AT 250 WORDS)
